Hp thunderbolt 2 card cable

[MicVilla]

Can anyone tell me where I can get this cable  or good close up picture and cable wire diagram layout the cable to make my own.

search this forum, using the keyword "thunderbolt" and you will find previous posts, several of them have information on the z820 cable

I see you have tagged the Z620 with your question.  My recall is that the interface cable to go from the Z620 motherboard over to the Thunderbolt card is different than what HP developed for the Z820 motherboard. HP had to reverse engineer those interface cables to use what traces were available on the different motherboards to get Thunderbolt to work on this family of workstations (which were engineered before Thunderbolt was a more matured technology).

A hint that might help is that the motherboards for the Z420 and Z620 are near identical and thus I'd search for both of those to try to find a pinout. DGroves knows quite a bit about this issue and may have some old breakthrough in his archives for the Z420/Z620 motherboards.

I sure wish someone would clearly post the solution to this... and someone may already have if you dig deep enough.  I don't personally use TB in these.

the picture the "OP" posted shows the z820 TBolt cable,....... and as far as i know both the z820/z620 use the same cable

Part Number: 751363-001 is for all HP Zx20/Zx30 Workstation lines

note: these HP TBolt card kits came with all 3 cables (Zx40, Zx20, Zx30) along with the TBolt card and the video bypass cable

Thank s everyone so far but I get my card on the second hand market and thought the cable would be easy to find, boy was I wrong. The part number usually get you a single USB header cable. But as far as my research shows the z620 need 2 USB header cable for it to function properly.So l thought someone with the cable can post the cable pin layout or detail photos of the cable so I can make my own.

Part Number: 751363-001 can hp just release the cable info to give there product a new life. HP please help us out here.

as "SDH" noted the z620/z820 motherboards were actually completed when HP decided to add Thunderbolt, as such the HP engineers had to work with what they had as a new motherboard was not going to be produced for this

this is why these systems have the weird cable and the requirement that the TBolt card must reside in SLOT 5

when the bios sees this card in slot 5, it reconfigures the two USB ports into the needed tbolt signals that the card requires

i told you to look at previous posts, did you? Taccess posted them a while back

Thanks very much this is great, with little probing and testing for the missing pins, I think I can make this cable. If successful I will post my results. Thanks everyone again for your help.

if your cable works please consider updating the current information with a updated pict/wiring diagram
